That might explain why Mark does not see panics (assuming the NFS client code has had more testing on sparc64 or similar architectures which does not seem unlikely (e.g. in the build cluster))... > I'm using a more or less current HEAD but the NFS code hasn't > changed that much since 8.0, at least it doesn't contain any > other alignment fixes I'm aware of. > I think I got what the problem is but I still haven't managed > to reproduce it so far.
